Hi there.
My power supply on my PC is overheating, so I decided to buy a new one.
I made sure that the one that I bought was ATX with 20pins and had the 4 pin
connector for P4. It does. The only difference between the old one and the
new one is that the new one is 450W and the old one was 300W. All of the
cables and connectors are the same.
I disconnected the old PSU and installed the new one, everything is plugged
in exactly as it was previously. I push the button on the front of the
machine and nothing happens - no lights, no fans, no beeps, nada. I
reconnect the old PSU, and it works (although it still overheats after an
hour or so)
Have I been unlucky and been sold a faulty PSU, or is there something else I
should try before I take it back?
Thanks.

Is there an on/off switch on the rear of the PS???? |

also, look on the back of the PS. is there perhaps a little slide switch
used to set the AC voltage?
If so, they are ususally shipped with it in the 115vac position, but I have
heard of the switch being set to 220 or whatever rather than the needed
115vac setting.

Thanks to both of you for getting back to me.
The voltage is set to 230V (I live in the UK, so this is correct)
There is a power switch on the back, it is set to the on position. I tried
in both the on and off positions in case the switch was labelled
incorrectly.
Is there a maximum wattage that can be connected to a motherboard? The
reason I ask is because both PSUs are the same brand, but the new one is a
more powerful model and output is the only obvious difference between the
two PSUs.
Thanks
Tom

I am pretty sure you are right. I was just unlucky I guess.
I shall take it back and ask for a replacement. Thanks for your advice.
